Marcel Offermans commented on ACE-301:
--------------------------------------
Thanks for this feedback, Tuomas, you are completely right, we should implement your suggestions
to make it easier to get started.
> Improve getting started html to avoid class/source incompatibilities with jdk7

> Key: ACE-301
> URL: https://issues.apache.org/jira/browse/ACE-301
> Project: ACE
> Issue Type: Improvement
> Environment: eclipse with jdk 1.7.0_07
> windows with jdk 1.6.0_33
> ant 1.8.x
> Reporter: Tuomas Kiviaho
> Assignee: Marcel Offermans
> Priority: Minor
>
> I'm new to ACE and BndTools and found out that building of the project from trunk required
a bit more steps than what was documented on getting started.
> *Command line build*
> ANT build process goes as far as deployment verifier with the environment specified in
this issue. Then you start getting error like below.
> {code}
> [javac] warning: [options] bootstrap class path not set in conjunction with -source 1.5
> [javac] src\org\apache\ace\deployment\verifier\impl\VerifyEnvironmentImpl.java:125: error:
type ServiceReference does not take parameters
> [javac] public ServiceReference<?>[] getRegisteredServices() {
> [javac] ^
> {code}
> osgi.core;version=4.3.0.201102171602 used in deployment verifier isn't compatible with
jdk7 (it's compiled with JSR14 flag). You might want to consider using 4.3.1.201210102023
from maven central which is intended to fix this.
> *Eclipse with Bndtools*
> Everything works fine until after you've created distributable archive and try to run
it using the provided shell script using the environment specified in this issue.
> {code}
> java.lang.UnsupportedClassVersionError: org/apache/ace/configurator/Activator : Unsupported
major.minor version 51.0
> {code}
> I suggest that getting started guide would include steps for configuring JDT which I
believe was previously provided automatically by M2Eclipse. I also noticed that defaults.bnd
contains javac.source/target as 1.5 which I believe should be 1.6.
